Roller adjustment
During pump operation as the hose starts to wear, internal leakage inside the hose can occur. In
order to avoid this, roller adjustment can be performed in order to increase the compression of
the hose. This is an important procedure, as internal leakage reduces the hose lifetime and affect
the pump flow. The adjustments vary based on pump rotation speed, discharge pressure and
liquid viscosity. This operation can be done without complete pump disassembly.
NOTE!
Proceed with this procedure only after familiarizing oneself with the instructions at the
beginning of chapter 3.
